BURGLAR-ALARM.

SPECIFICATION forming part of Letters Patent No. 284,980, dated September 11, 1883.

Application filed March 12, 1883. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. REIFF, of the city and county of Philadelphia, Pennsylvania, have invented an Improvement in Burglar-Alarms, of which the following is a specification.

' My inventionhas reference to burglar-alarms adapted to be put in action by' the opening of a door, window, 8m; and it consists of a telescopic barrel, the lower part of which carries the anvil and the upper part the cartridge, this latter being formed of a tube having its mouth closed and apertures arranged in its sides at or near the middle, and in many details of construction, all of which are fully set out in the following specification, and shown in the accompanying drawings, which form part thereof.

The object of this invention is to provide a signal device against burglars and thieves, and to so form it that a large blank cartridge may be used therein without danger of setting fire to the house or any articles in the room; also, to increase the noise produced by the explosion.

In the drawings, Figure 1 is an elevation of my improved burglaralarm before firing. Fig. 2 is a sectional elevation of same on line 00 00, and shows how the same may be attached to the door, and Fig. 3 is a perspective view of the device for supporting the alarm in the door-jamb.

A is the lower and larger tubular part of the alarm, and has its bottom closed by an anvil-plug, B, rounded on the bottom I), and provided with the discharging-point 0 upon its upper surface. The upper part of said part B is provided with slot D, having a curved outlet, (1, to the upper edge of the body. The upper part, E, of the alarm forms a tubular barrel adapted to slide into part A, and has its lower end closed with a plug, J, having an aperture, K, to receive the cartridge L. Near the bottom is a pin, I, which works in the slots D and d, to couple the parts A and Etogether to form a telescopic joint. The upper end of barrel E is also closed by a plug, F, to which may be secured a supporting-ring, G, and at or near the middle said barrel is provided with one or more apertures, H.

0 represents the door-frame, and N the door. A piece of wire, M, bent at M to form shoulders m and a hook, M is placed between the frame 0 and door N, as shown in Fig. 2, and the alarm is hung to the end by a string,

The parts A and E being separated, a cartridge, L, is placed in the plug J of part E, and they are then coupled together again, as shown, and hung upon the wire M. Now, should the door-be opened, it presses on the shoulders at and pulls out the wire M, allowing the alarm to fall to the ground. This causes the two parts to telescope, and the point C explodes the cartridge L. The smoke and sparks ascend the barrel E, but upon meeting the plug F they are turned back to find escape by apertures H, but not until all danger from fire is past. In addition to pro tecting articles from fire, the closed barrel magnifies the noise produced by the explosion.

I do not limit myself to the small details of construction, as they may be modified or dispensed with, if desired, without departing from my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of body or part A, pro vided with anvil 13, having point C at its bottom and slot D at its top, long tubular barrel E, closed at its top, open at its middle part, and provided at its bottom with a receptacle to contain the cartridge, and pin 1, to work in slot D, substantially as and for the purpose specified.

In testimony of which invention I hereunto set my hand.

WILLIAM H. REIFF.
